BENJN. W. WARNER, OF NEW YORK, N. Y.

TAILoRs SHEARS.

Specification of Letters Patent No. 6,008, dated January 9, 1849.

To all whom t may concern:

Be it known that I, BENJAMIN W. WAR- NER, of the city of New York andState of New York, have invented certain new and useful Improvements inthe Mode of Constructing Shears for Cutting Cloth or Other SubstancesUsually Out by Means of Shears; and I do declare the following to be atrue and exact description.

The nature of my invention consists in attaching the lower blade of theshear to a bar and making it work incombination with the upper blade bymeans of a short arm or lever worked by the upper hand lever ashereinafter described, by which arrangement the blades are made to actin cutting more nearly parallel to each other than those of the ordinaryshears thus increasing the facility of their use by lessening the spreadof the points, and keeping the lower part of the shears constantly incontact with the surface upon which the material is laid to be cut atthe same time that the power of the hand is applied more equally overthe whole blade than in any other plan hitherto in use. A drawing motionis also'given to the upper blade by this arrangement, which renders thecut more perfect and easier.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

I make the upper blade and the levers, worked by thehand, substantiallyas they have hitherto been made. The lower blade I make upon the end ofa bar, represented by the annexed drawing (a, a,). I connect the lowerblade and bar to the upper hand lever by means of a joint, representedby the annexed drawing at This joint should be placed at la convenientdistance from the pivot; for an ordinary tailors 'shears say at thedistance of an inch and an lmaterial to be cut.

In order to securezthe blade in a xed po sition, as well as to enable itto have a forward and backward motion such as would be given .by theaction of the lever I provide the end of the bar farthest from the bladewith a slot seen at (o) of the drawing i referred to, through this slotI pass a screw into the rim of the lower lever, allowing a .j playbetween the head of the screw and the slot sufficient to allow therequisite motion of the bar. v i i Ihe accompanying drawing represents atailors shears with my improvements.

What I claim as my invention and desire to secure by Letters Patent isl1. The construction of the lower bladeseparate'from the upper lever andlconnected with it-by a joint a above described.

2. I also claim the applicationof the bar to steady the vaction of thelower blade con` structed andoperating as herein described;

and also the combination of the lowery blade with thev upper hand leveryin the mode of application described. e BENJAMIN W. WARNER. Witnesses: l
